Description

Technical Field

[0001] This utility model relates to the field of injection molding technology, and more specifically, to an injection molding device for producing rubber sleeves. Background Technology

[0002] During the production process, residues of plastic or other raw materials can easily adhere to the inner wall of the supply pipe. These residues can affect production efficiency and product quality during injection molding, especially for precision injection molded products such as sleeves. If the residues are not removed or cleaned in a timely manner, they can lead to poor flowability of the raw materials during production, affecting the injection molding effect and the surface quality of the final product. In addition, the adhesion of residues can cause uneven flow of raw materials, which may lead to problems such as raw material blockage and unstable flow during production, and may even have an adverse effect on the injection mold, increasing cleaning and maintenance costs.

[0003] Air bubbles in the supplied raw materials are another common technical challenge. Air bubbles may form because air is not completely removed during mixing, melting, or conveying of the raw materials, or because improper temperature control prevents complete evaporation of gases during melting. The presence of air bubbles affects the flowability of the raw materials, resulting in uneven injection molding and consequently affecting the density, surface smoothness, and strength of products such as sleeves. Air bubbles may expand or become trapped inside the sleeve during injection molding, leading to product defects such as air bubbles and cracks. This is especially problematic for products requiring high precision and quality, as air bubbles negatively impact both functionality and appearance. Utility Model Content

[0021] Please see Figures 1-5 An injection molding device for producing rubber sleeves includes a flow pipe 1, a vibration and hammering mechanism, a lifting and adjusting mechanism, and a fixing and snapping mechanism. The vibration and hammering mechanism includes a lifting plate 2, a drive motor 3, a rotating rod 4, a pushing rod 5, reciprocating blocks 6, and a hammering pad 7. The lifting plate 2 can slide longitudinally on the outer wall of the flow pipe 1. The rotating rod 4 is installed at the output end of the drive motor 3. One end of the pushing rod 5 is rotatably connected to one end of the rotating rod 4. Multiple sets of reciprocating blocks 6 are arranged radially at the top end of the lifting plate 2. The hammering pad 7... Installed on the side of the reciprocating block 6, the hammering pad 7 contacts the outer wall of the flow pipe 1. The lifting adjustment mechanism includes a side fixing plate 8, a first clamping plate 9, a second clamping plate 10, an adjustment hole 11, a clamping pipe 12, and a clamping rod 13. The side fixing plate 8 is installed on the outer wall of the flow pipe 1. The first clamping plate 9 and the second clamping plate 10 are installed at the bottom end of the lifting plate 2. The first clamping plate 9 and the second clamping plate 10 are slidably installed on the side fixing plate 8. Multiple sets of adjustment holes 11 are provided on the side fixing plate 8. The clamping pipe 12 is installed on the side of the second clamping plate 10.

[0022] In this embodiment, the drive motor 3 drives the rotating rod 4 to rotate through its output end. One end of the rotating rod 4 is connected to the push rod 5, causing the push rod 5 to rotate. The rotation of the push rod 5 drives multiple sets of reciprocating blocks 6 to slide centripetally at the top end of the lifting plate 2. A hammering pad 7 is installed on the reciprocating block 6. The hammering pad 7 contacts the outer wall of the flow pipe 1 and hammers the outer wall through reciprocating motion. The lifting plate 2 can slide longitudinally on the outer wall of the flow pipe 1, which allows the hammering pad 7 to hammer at different positions in the flow pipe 1, ensuring that the production process of the rubber sleeve is sufficiently vibrated and hammered. Through the cooperation of the clamping tube 12 and the clamping rod 13, one end of the clamping rod 13 extends through the adjustment hole 11 and quickly clamps with the first clamping plate 9, the second clamping plate 10 and the clamping tube 12. When the locking rod 13 extends into the adjustment hole 11, the first clamping plate 9 and the second clamping plate 10 are fixed at the bottom of the lifting plate 2, thereby ensuring the stable position of the lifting plate 2. Through the cooperation of the locking tube 12 and the locking rod 13, the operator can adjust the height of the lifting plate 2.

[0023] The fixed locking mechanism includes a locking groove 14, a rotating ring 15, a rotating block 16, a clamping plate 17, and a locking rod 18. One end of the locking rod 13 can extend through the adjustment hole 11 and cooperate with the first clamping plate 9 and the second clamping plate 10 to quickly lock into place with the locking tube 12. The locking groove 14 is set on the outer wall of the locking rod 13. The rotating ring 15 is rotatably mounted on the outer wall of the locking tube 12. The rotating block 16 is mounted on the top end of the rotating ring 15. The clamping plate 17 is mounted on the side of the rotating block 16. The locking rod 18 is laterally slidably mounted on the outer wall of the locking tube 12. One end of the locking rod 18 is slidably connected to the clamping plate 17. The rotating clamping plate 17 causes the locking rod 18 to extend into or away from the locking groove 14.

[0024] In this embodiment, to maintain the stability of the mechanism during the lifting and adjusting process, one end of the locking rod 13 extends into the adjusting hole 11 and engages quickly with the first clamping plate 9, the second clamping plate 10, and the locking tube 12. The lifting plate 2 is stably held in the required position. The rotation of the rotating ring 15 drives the rotating block 16 and the clamping plate 17 to move together. The movement of the clamping plate 17 causes the connection position between the locking rod 18 and the locking groove 14 to change. The locking rod 18 engages with the clamping plate 17 by sliding laterally on the outer wall of the locking tube 12. The rotation of the clamping plate 17 causes the locking rod 18 to extend into or away from the locking groove 14, further fixing the locking rod 13 and preventing the lifting plate 2 or other components from loosening or shifting. The fixing and locking mechanism ensures a firm connection between the lifting and adjusting mechanism and other components through rotation and sliding adjustment.

[0025] Please see Figures 1-5 As a supplementary embodiment of an injection molding device for producing rubber sleeves, which includes a vibration hammering mechanism, a lifting adjustment mechanism, and a fixed clamping mechanism: An upper outer pipe 301 and a lower outer pipe 19 are installed at both ends of the flow pipe 1, and are connected to external material supply equipment and material demand settings through the upper outer pipe 301 and the lower outer pipe 19. A sliding rail 20 is installed at the top end of the lifting plate 2, and a reciprocating block 6 slides on the sliding rail 20. An installation platform 21 is installed at the top end of the lifting plate 2, and a drive motor 3 is installed on the installation platform 21. A connecting plate 22 is installed at the bottom end of the side wall of the clamping pipe 12, and the connecting plate 22 is fixedly installed on one end face of the second clamping plate 10. A bottom ring 23 is installed at the top end of the connecting plate 22, and a spring pin 24 is installed on the bottom ring 23. Multiple sets of spring pins 24 are provided. A top groove 25 is opened at the bottom of the rotating ring 15, and one end of the spring pin 24 extends into the top groove 25 for rotational support.

[0026] More specifically, firstly, both ends of the flow pipe 1 are connected to external material supply and demand equipment via upper external pipe 301 and lower external pipe 19, ensuring that materials can smoothly enter the device for injection molding production. The drive motor 3 starts, and the rotating rod 4 drives the push rod 5 to rotate, pushing multiple sets of reciprocating blocks 6 to slide at the top of the lifting plate 2. The hammering pads 7 on the reciprocating blocks 6 contact the outer wall of the flow pipe 1, helping the plastic material to flow evenly or fill the pipe through vibration and hammering. According to production needs, the operator adjusts the height of the lifting plate 2 via the clamping rod 13, thereby changing the position of the hammering pads 7, ensuring that the vibration hammering mechanism can hammer at different heights. The fixed clamping mechanism ensures the stable connection between the clamping rod 13 and each component. Through rotation and sliding adjustment, it ensures that the lifting adjustment mechanism does not loosen during operation, maintaining the stable operation of the entire device. With the cooperation of vibration hammering and lifting adjustment, the entire injection molding device can efficiently and stably produce and process plastic sleeves.

[0027] In summary, during the use or operation of the overall equipment: when the vibration and hammering mechanism is required, the hammering pad 7 contacts the outer wall of the flow tube 1, aiding in the injection molding process of the plastic sleeve. The drive motor 3 drives the rotating rod 4 to rotate through its output end. One end of the rotating rod 4 is connected to the push rod 5, causing the push rod 5 to rotate. The rotation of the push rod 5 drives multiple sets of reciprocating blocks 6 to slide centripetally at the top end of the lifting plate 2. The hammering pad 7 is installed on the reciprocating block 6, which contacts the outer wall of the flow tube 1 and hammers the outer wall through reciprocating motion. The lifting plate 2 can slide longitudinally on the outer wall of the flow tube 1, allowing the hammering pad 7 to hammer at different positions in the flow tube 1, ensuring sufficient vibration and hammering during the production process of the plastic sleeve. The vibration and hammering mechanism provides vibration and hammering to the outer wall of the flow tube 1, which helps in the uniform flow or filling of plastic materials.

[0028] When the lifting adjustment mechanism is needed, the position of the lifting plate 2 is adjusted and fixed to ensure the normal operation of the vibratory hammering mechanism. Through the cooperation of the clamping pipe 12 and the clamping rod 13, one end of the clamping rod 13 extends through the adjustment hole 11 and quickly engages with the first clamping plate 9, the second clamping plate 10, and the clamping pipe 12. When the clamping rod 13 extends into the adjustment hole 11, the first clamping plate 9 and the second clamping plate 10 are fixed at the bottom of the lifting plate 2, thereby ensuring the stable position of the lifting plate 2. Through the cooperation of the clamping pipe 12 and the clamping rod 13, the operator can adjust the height of the lifting plate 2 to ensure that the vibratory hammering mechanism can vibrate and hammer at different positions. The lifting adjustment mechanism makes the position of the lifting plate 2 adjustable, so that the vibratory hammering mechanism can be adjusted according to production needs.

[0029] When the locking mechanism needs to be fixed during operation, to maintain stability during lifting and adjustment, one end of the locking rod 13 extends into the adjustment hole 11 and engages quickly with the first clamping plate 9, the second clamping plate 10, and the locking tube 12. The lifting plate 2 is stably held in the required position. The rotation of the rotating ring 15 drives the rotating block 16 and the clamping slope plate 17 to move together. The movement of the clamping slope plate 17 changes the connection position between the locking rod 18 and the locking groove 14. The locking rod 18 engages with the clamping slope plate 17 by sliding laterally on the outer wall of the locking tube 12. The rotation of the clamping slope plate 17 causes the locking rod 18 to extend into or away from the locking groove 14, further fixing the locking rod 13 and preventing the lifting plate 2 or other components from loosening or shifting. The locking mechanism is fixed by rotation and sliding adjustment to ensure a firm connection between the lifting and adjustment mechanism and other components.

[0030] First, the two ends of the flow pipe 1 are connected to external material supply and demand equipment via the upper external pipe 301 and the lower external pipe 19, ensuring that the material can smoothly enter the device for injection molding production. The drive motor 3 starts, and the rotating rod 4 drives the push rod 5 to rotate, pushing multiple sets of reciprocating blocks 6 to slide on the top end of the lifting plate 2. The hammering pads 7 on the reciprocating blocks 6 contact the outer wall of the flow pipe 1, and help the plastic material flow or fill evenly in the pipe through vibration and hammering. According to production needs, the operator adjusts the height of the lifting plate 2 through the clamping rod 13, thereby changing the position of the hammering pads 7, ensuring that the vibration hammering mechanism can hammer at different heights. The fixed clamping mechanism ensures that the connection between the clamping rod 13 and each component is stable. Through rotation and sliding adjustment, it is ensured that the lifting adjustment mechanism does not loosen during operation, maintaining the stable operation of the entire device. With the cooperation of vibration hammering and lifting adjustment, the entire injection molding device can efficiently and stably produce and process the plastic sleeve.

[0031] Of all the solutions mentioned above, those involving the connection between two components can be selected according to the actual situation, such as welding, bolt and nut connection, bolt or screw connection, or other known connection methods, which will not be elaborated here. For all the fixed connections mentioned above, welding is preferred. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this utility model. The scope of this utility model is defined by the appended claims and their equivalents.
